Tell me what I need to notice. Point it out. Adjust things for me. It might be in a blind spot. And don't just say "racist!", because it doesn't really do the job you wish it to. I'm actually challenged to think that some so called 'racism' or what is part of what is called "racism", isn't 'good' (not that some isn't bad).
But anyways, what do I need to notice?
Should I not notice that I am more likely to get robbed by a black person than a white, in my town? That more black people currently commit violent crimes against whites than vice versa (multiple times higher). Just ignore it? Make excuses? I do that. But there comes a point... Where I just don't think it should be my problem.
Should I not notice how much pressure is on the E.U. countries to accept wave after wave of immigrants from countries far and wide and near? And how people, white people are shamed for wanting to preserve themselves, their culture, their heritage, their race, and not be outbred in their fucking homelands by foreigners. When else has on such a wide scale this happened? Invasions. Colonization. Not to say places haven't existed. Crossroads. And not that I don't see, I guess, how white countries are attractive, or hate anyone for going to them, or blame them. Fuck. I'm in conflict.
You can disassemble this and point out that 'racism' could exist or those behaviors could even among people who identify as white, for each other, or who others think are among the same. That its all rather grey when it gets down to it in ways, I know that. ...
You need to notice that criminal and antisocial behaviour is more to do with complex socio-economic and socio-political circumstances than simple things like ethnicity, religion or race.
You need to notice that "white culture" is not under any threat. International movement has been taking place for thousands of years and we still live with cultural diversity.
You are right, it is grey indeed. Because of this, not despite it, is why the assumptions at the base of many of your concerns are misled.
